### Re: piramid - piramid = 1 kokonut

@integer This is my interpretation of the description given by bluatigro. You have a four sided stack of coconuts (or cannon balls) of a certain height containing X amount of coconuts and you need to construct a three sided stack with X - 1 coconuts. How many are needed and how high are the stacks. ...

### Re: Bresenham3D

BasicCoder2 Your program contains for i as integer = 0 to l that should be for i = 0 to l . The i in for i as integer = 0 to l is a different one then the one in dim as integer i . Here is a other Bresenham in 3D that is much simpler. You should have a look there, it's a simple clear page with simpl...

### Re: Sha-256 QB

I don't have at this moment time to give a explanation of the changes I made but it should not be hard to spot them. The extra code makes the program slow but there is room for some speedup. 'SHA-256 OPTION EXPLICIT FUNCTION SHL&(x AS LONG, n) ' SHL& = x * 2 ^ n DIM x1 AS DOUBLE IF x < 0 THE...

Thanks for the code example, the only thing I knew that it needed a constructor through the error messages I got from my try's. But I had no idea how and where to put it.

### Re: Always for me a Big question

Gmp_int.bi has two problems in the floating point division (/) routine. First the gmp floats need a 16 byte structure (__mpf_struct) but they get a 12 byte structure (__mpz_struct) which result in data stored outside the structure and most likely overwriting data in the next structure, hence crashes...

### Re: Calendar Calculations Class

rpkelly Had a look at your code, nice piece work. At the end of the file you have a function for ceiling a floating point. My suggestion is to replace Function = cmFloor(x * -1) * -1 with Function = -cmFloor(-x) . This will replace two multiplications with two sign change instructions. ' ===========...
